1n proceeding in accordance with the present invention a suitable frame 1 is employed upon the top of which is mounted a paper roll feeding and cuttin device which includes a paper roll 2, igures 1 and 17). The paper P is fed downwardly from the roll 2 and passes over guides 3 and 4 and then downwardly between upper opposed feed rolls 5.

Co-operating cutter rolls 6 are located below rolls 5, one of which rolls 6- has a cutter 7 entering a groove 8 in the opposed roll so as to cut the paper into pre-determined lengths. lhe paper sheets are, prior to cutting@ received in between the guides 9 and also between lower segmental eed rolls 10. Screws 11 are employed to enable adjustment or the tension exerted by lthe several feed and cutter rolls on the paper. The cnt sheet et paper h is received and held in a pair oi guides 12. The engagement of the sheets by the rolls 10 alter cutting causes a slight speeding np oi the movement of the ont sheets.

lhe butter which themachine is designed to wrap is otfrectangnlar or bar term, as indicated at B (Figures 2, 19, 2O and 25), so as to be readily cut into blocks, or squares, tor serving, as indicated in lliignre 25.

The butter bars are initially placed on a horizontal table 13, rovided at one end ot the frame 1, and which has a side guide 14, preferably ot maple wood, to engage the bars at one end. Ylhe batter bars are advanced step. by step over the table 13 and.'

successively moved into engagement with a sto 15 at the forward end ot the table, which stop serves to arrest the movement ot the toremost butter bar in properly aligned position within a vertically movable receiver 1t, disposed at the torward end ot the tableu "lhe .receiver 16 is carried by a slidev 17 which is movable verticallyA in a guide 18 andconnected to a roclrer arm 19 mounted on a shalt 20. ythis shalt has an arm 21 operated by arod22 whchis connected to and actuated rby a rotation ot the cam 23 on the cam shaft 2l. The receiver 16 has a stop 1? on the upper end portion of the rear side thereol, 'whichA stop serves to prevent a torvvard movement el the butter bars when the receiver is lowered :trom receiving position.. y

lhe means tor imparting Ya step-by-step advancing movement to the batter bars over is supported and gnided tor horiaontal movements and given vertical movements by rollers 31 carried by torlred arms 32 disposed at opposite sides oil the arm 27; the

arms 32 being pivotally mounted on. respective sbatte 33 and being pivotally connected by a rod to canse them tovhave rocking movements in. unison. The 'liront arm: 32 has a lng 35 pivoted to rod 36, the latter being actuated by cam d? on the cani menace shalt 24. it coiled tension spring 29 is. vconnected to table 13 and to rod 29, and acts l on said rod to take, up lost motion.

The butter bars B, which are advanced .horizontally spaced relation lengthwise ot the trame 1, except that they are broken at points where the wrapper sheets l? and the cartons are ted intofwrapping position, as hereinai'ter described.

Slightly in. advance oil the receiver 16 above and at the sides ot the guide bars to are disposed side guides 38, preterablv of maple, for engagement with the ends ot the butter bars to assist in guiding the movements oi the same as they are advanced over the bars 48. rtlm guides 38 are pivoted at 39 to arms t0, the latter in tarn being pivoted at l1 to the machine (liigare'2).`

@oiled springs t2 tension the guides 38, movement ot vthe latter under the spring action being restricted by limiting rods '-lfl. A top guide at, preferably ot maple, is disposed between the guides and is hingedly 'carried' at itsprear end by a shaft t5 mounted at its ends in standards t6 on the trarne 1. A springI t6 acts on the shalt t5 to cause the topgnide tt to exert a light downward pressure on the top otn the butter bars as they pass thereunder.

llmmediately in advance ot the guides 38 and it are disposed the guides 12 tor the cut paper sheets P", said guides extending down through the bottom guide bars t8 so that a vsheet Pt' is disposed in the path of movement ol' the butter bars overv the guide bars l 48.' rllhe butter bars are progressively ads vanced to the machine 'by .means hereinafter described, being hrst advanced, in the present instance, from the receiver 16 to n point where it is held by the-guides 38 and lll@ it immediately at the rear et a cnt paper sheet l disposed in the guide 12. The next advancing movement ot the hotter causes it to pass over the guldes 12 and to carry the sheet ll", with it, the *sheet being engaged midway between-the top and bottom Y thereot. its the sheet is advanced with the butter bar the port-ion thereot above the lintter bar is engaged by the carved endv and bot' 'tom ot a guide orpresser member t9 (Figure 17) and v`tolded rearwardly over the top ot the butter bar, while th'epoitionoil the vsheet projecting below the batter bar is engaged by a folding member t8? and folded rearwardly under the biitter bar. During a con tinued advancing oi the butter bar and sheet over' the guide bars te, the end leiding tongueshl',o0 and t@ engage the ends ot the wrapper sheet and move the latter inwardly 'against the 'ends ot the butter litt) lith During -the operation of the end folding tongues 51, -a pressure foot 100 exerts a light downwardpressure on top of the but-` ter. (Figures 2 and 4) pivoted at 102th a bracket 103, the latter having a stop 104t0 limit thcj..

upward throw of .the lever.V

The lever is operated by a. spring'tension. rod" 105, the rod in-turn being operated by a' cam 106 on ashaftt disposed lengthwise in the lower portion of the frame 1. The

` lower end of the rod. is forkedv at 109 .and-- are previously turned in by the tongues 51,

slidably straddles the shaft 66 and also lcarries a roller 110 engaging on 'the upper. sur-p face of the cam 106.A The folding tongues 49 are mounted yfor yielding outward movements and such. movements are'resisted bv springs49 (Figure 2) actingagainstbell ,crank levers 49b fulcrumed inV the Vframe 1 and havingan arm'connected tothel respectire-tongues 49.- The folding tongues 50 are 5 50 and 49, so as to lie against therearvertiical side of the butter bar. The punches 51L are horizontally slidable in 'guides120' and are operated by bell-cranks 121. the latter being actuated by'reds 122. The rods 122. are tensioned by springs 123' and are aetuated by rollers 124 engaging cams '125, lthe lower ends of the rods122 beingforked at 126 and slidably straddling shafts 66 and 187 on which the. cams are mounted. A tensioning plate 52 exerts a light downwardV pressure on the top of the butter bar while in and moving to the position where the ywrapper is actedv on by the'punches 51a. The pressure plate 52 is carried by a top guidev plate 52.. The plate 52a is removable to permit cleaning and is held in position a.

yielding-pressure foot 52b engagingm 'a slotted guide 52 on the plate top. -The pressure foot is swingingly vrcarried by a The means for advancing the butter through the.' paper wrapping and carton folding parts of the machineis shown in Y ...and is actuated by a movement of the rod 64 Figures 19 .and 20 and includes a reciprof cally movable bed 53 having a series of L- vshaped pushers 54j projecting upwardly therefrom and 'formed withfvertlcal faces 55 similar series'of shorter pusher' members 56 having vertical faces 57 L Thebed 53 has The foot is carried by a lever 101' an valigned the upper panels H and H and lower panels horizontal as well as vertical reciprocatory movements, its path of movement being shown in dotted linesin Figure 20 of the drawings asbeing first forward in butter bar pushing position, then backwardly a short distance,- then downwardly and rearwardly and then upwardly andagain for- `wardly. The slight backward `movement [shown at Z in F1gure20 is ,to retract the pusher members from between the upper and lower folds Pa" and .Pb of the wrapper sheet before thedownward movement of the bed. The means for operating the bed 53 is shown in Figures 27 and 28 and includes two pairs of bell cranks 128 pivoted 'at 129 to the frame of 'the machine and having rollers 130 which engage tracks' 131 .carried on the under face of theJbed. The pairs of.

bell cranks 128 are connected by horizontal rods 132 to arms 133 of rock shaft 134. The

shaft 134 has an arm 135 affixed thereto, and

,to which latter .is.pivoted a rod 136 driven from'a cam 137 on a shaft 138. The bed, ppon a rocking of the'bell crank levers 12S, 1s alternatelyv vraised and lowered, yand in vorder tolreciproca'te'same during the inter-y vals of raising and lowering the rod 139 is employed and, has a T-head 140I pivotally connected tothe bed. The rod 139 is actuv tolle placed .in vthe pasteboard carton.

Referring, now, `to Figures land 17, the

"carton blanks E are placed'in the hopper 58 and are .fed downwardly by means of feed rolls` 59 and 60 and into a guide 61a which extends down through the guide bars 48. l

' A carton E when in position in the guide 61a extends with its center 'panel F in the path of movement with the butter' bars through the machine.l When a butter barl isarlvanced from the position() by anVY adjacent pusher 54, it engages the center panel F of carton and causes'a doubling of G and G respectively over and under the butter har, due to' the forcing `of the bar and carton forwardly between the rollers 61; the bar andcarton-being advanced hv such movement to a point under the `shaft 63. This shaft `carries folding fingers 62A to rock the. fingersv62 downwardly to fold the topedgeilap H down at the yrear of the butter bar. Therod 64' has a roller` 64, which engages and is operated by a cam 65 on the shaft 66. lAs shown inFigure the rod 64 has a yoke 36",y the latter tensoned by a spring67 to exert an upward pull on the rod and yoke. The next butter bar advancing movement of the bed 53 causes the cross-arm provided at the lower end'portion dll i ment ol the pusher. 'lhe arm 186 is pivoted of the hrst pusher66. The shafts 69 are provided at their lower ends with armsa carrying rollers 170 engaged by cams 17l, rigidly lined to the frame ot the machine, the arms 70a being tensioned ley a spring 171a to cause the rollers 170 to yieldingly bear outwardly against the cam laces. The cams 171 arc adjnstahly supported by brackets 72, controlled by bolts 7 3 (Figure 2). ,i

As the rollers 17 O pass along the cams 17 l during an advancing movement of the pusher 56, the folding lingers 68 are swung inwardly to cause a folding ot the end flaps il against the vend ot' the wrapper butter A'shaft 172 (Figures 2, 7 and 27) is located slightly in advance ot the shalt 63', and carries arresting or stop fingers 173 which extend in the path ot movement of the butter bars and stop each butter bar as it moves Vintoposition to be acted on by the folding finger 62. 'lhe movementot the shafts 17 2 and 68 are so timed that the stop fingers i73- will act to stop a butter bar in position for the hnger 62 to act on the carton llap lil thereof 'and to oppose. such leiding action.,` the stop lingers A178 and 62 being then raised to inoperative position at approximately the same time.. The shalt 172 is connected by van arm 178'l to a rod 174i which extends downwardly trom the arm and has a yolre 175 at its lower end which straddles the shalt 66 and carries a roller 179 below the shalt in engagement with the periphery ol a cam 178. il. spring 17 7 acts on the rod 17d to normally retain the roller 179 in engagement with the cam.'

Atterthe folding ot the topot dap H by the lingers 62 and betere the raising movement ot such lingers, an L-sliaped arm 186 (Figures 2 and 6) is swung down lor its tree end to engage thedlap l-l" and hold it in folded position (ses Figure 22)I until 'the adjacent pusher 56 at the beginnlng ot its next forward strolre has engaged the lower edge Hap H. The holding arm 186 then immediately raises so as not to intertere with the continued'ndvancing moveto a top member 77 ot the trame at 181 and 'is connected at its inner'end to a downwardly projecting rod 182 having ayoke 183 at its lower end which straddles the shaft 187 and carries a roller 184 above the shaft for engagement with theperiphery of a-cam 186 on the shaft. A spring l85acts on the rod 182 to normally 1n engagement with the cam.

During the advancing movement of a butter bar and its wrapper parts fromvthe position in which the .edge Haps H and Gf were folded, the folding lingers 68 act on the end deps J to hold them inwardly l agamst the ends of the butter bar, as heref mbefore described, and when the butter bar is near thek end of such advancing move-` ment the end flaps K ot the carton engage the .stationary folding members 76 (Figures 2 and 9) and are folded inwardly therehy. Atthesame time, the lett hand end flap. L moves under a stationary folding anvil 92 (ligures 2 and 8). A presser member 77 is carried at its iront end by the cross member 77*1 being-connected at its trent end to the bracket member 7 7 a by a bolt 77b and at its Jforward end to a bracket 7 8 which 1s disposedat the forward end of the ma.- chme (Figure 2). 'll`his` presser member exerts' a yielding pressure on the top ot the carton alter the butter bar passes under the same during the remainder ot its movement through the machine. 'l'he member 77 has fa dat spring presser plate 242 secured there. to,` the latter extending beyond the sides of the bar and having its ends 2li curved up` ward and toward each other over the har which projects therethrough.,

When the butter bar is in the position shown in Figure 8, with the end deps l., thereof respectively over and under the anvils ill and 92, the tongues M ot such tlaps are bent downwardly and upwardly respectively at the side edges ot the anvils by the tolding` linge-rs 79 rand 86. 'llhese lingers are carried respectively by arms 8l and 82 which are pivoted at their outer ends at 83 and 8d respectively to the trame and are pivotally connected intermediate the ends to rods 85 and 86. rlhese rodsentend downward and have yolres at their lower ends which straddle the respective shafts 66 and 187, the rod 85 being provided with a roller which acts on the top ot a camll on the shalt 66, and the rod 86 having a roller which acts on the lower arc ot a cam 90 on the shalt 187. 'The 4reds are respectively tensioncd ley springs 87 and 88 to hold the respective rollers in engagement with the earns. 'lhe action of the cams on the rods 85 and 86 is such that the folding arms 81 and 82 have respective downward and upward folding movements imparted si1nnltaneously thereto to cause the tree ends oi' the arms to engage and told the tongues M downwardly and upwardly respectively at the sides ol the anvils 91 and 82.

Alter the folding action ot the carton tongues M, the carton is advanced hy one retain the roller l lll@ of the pushers 56 to the position shown-in Figure 9 where the end aps L are folded inward against the ends of the butter bar and the. tongues ,M of such flaps inserted within the-cartonbody t `retain the carton 1n folding relation to the butter bai-. `As the carton is advanced to this folding position,V the end edges of the tongues are engaged by respective curved guides 75 and 76 and guiding tongues 75a and 7 G projecting therefrom, the left-hand guide extendmg outwardly and upwardly from the bottom of the carton and the right hand guide extending outwardly and downwardly from the top of the carton. The engagement of the tongues with the guides 75 and causes a slight inward bending of the tongues, as illustrated in Figure 14.Y The end. flaps L and tongues M when in this position are disposed under respective folders, each including a plate 150 pivoted at 151 to a casing part 152, `the plate being tensioned relative to the casing partby a..

spring device 153, which latter also actsl to limit the outward lpivotal' movements of the plates. The casings 152 are pivoted at 154 to brackets 155 carriesdfby the frame and are operated by arms 156 connected to rods 157. The rods 157 are tensioned by coiled springs 158 and have forked, or slotted, lower ends 159 which slidingly straddle respective lshafts 66 and 187, and are. provided with rollers 162,' one above and one below, and in engagement with'a respective cam.163 on the 'associated shaft.

1t is thus evident that the rods 157 are si,- multaneously operated; one to impart an upward folding movement to the right hand folding plate 150 and the other to impart a downward folding movement to tue' left hand folding plate 150, to cause the respective end iiaps L to be folded inwardly against the carton ends and the flaps M insorted into the carton one above the bottom panel G and the other below the top panel Il. The inserting movements -of the tongues M areguided by the plates -and 76, the inner surfaces of which register flush with the inner surfaces of the respective bottom andl top panels G and H, by reason of the depressed seats 270 formed in their inner surfaces to Vreceive the edge of the carton (see Fig. 14). This completes the folding operation, and the next advancing movement of the ,pusher means causes the last pusher member 56 to eject the carton and enclosed butter bar .from the machine.

The shaft 187-drives a beveled gear 188 (Figures 17 and 28) which meshes with a similar gear 189 on a shaft 190, the latter carrying sprocket wheels 191, 192 over which sprocket chains 193 and 194 (Figures 1 and 17) are respectively trained. The sprocket chain 193 drives the feed roll 60 of the carton hopper, while the chain 194 drives the sprocket 195 of the paper i feeding device, the sprocket 195 through -gears 195, 197, 198, 199 and-200, effecting a driving of the paper feed and cutting .rolls 5, 5, 6, 6, and 10, 10.

' The shaft 187 is driven by intermeshed bevelgears 201 and 202 (Figure 1), the latter driven by the motor 203 by means of i the gears 204 and 205 Figure 27)'.l The shaft 6G has a gear 200 (Figures 9 and 28) in mesh with a gear 207 on the shaft 210, the latter being in mesh with a gear 208 on the shaft 187, whereby the shafts 66 and frame and has a shifter arm 248 connected to a clutch shifting rod 249, whereby a clutch (not shown) on the shaft .204.` may be operated.

In operatioma supply of butter bars B.-

is placed'on the table 13 and this supply is maintained during the running of the machine. To start the machine, the operator th'rows either handle 243, 244 of the clutch shaft 245 to place the associated clutch in operating position. A rotation is then communicated to the shaft 24 (Figure 25) whereupon the feed member 13a through the arms 32 and cam 37 is given vertical and horizontal reciprocatory movements to successively raise and advance the butter bars in step by` step manner over the table. The butter 'moves forwardly with the forward movement of the feed member 13El and as soon as the receiver 16 has been synchronously raised vby the slide 17 to align with the butter bars on the table 13, the foremost butter bar is moved into the receiver and stoppedin proper position therein by engagement Withf'the stationary stop 15. The receiver 16 is then lowered to place the butter bar disposed therein in the plane of the bed 48 and below the stop 15, such movement of the receiver placing the stop 15a carried thereby in register with the butterbars on the table 13 so as to prevent a forward movement thereof until the receiver has returned to elevated position. When the receiver is in lowered position, the pusher means 53 is actuated to cause the rear pusher member 54 thereof to rise at the reary of the receiver so that upon the forward movement of the pusher member the butter bar in the receiver is advanced therefrom along the bed 48 and between the end guides 38 and below the top presser plate 44, the butter stopping shortly to the rear of the tissue wrapper sheet l), which has been fed across the path of movement of the butter bar and rests in the support 12. The next advancing movement of the pusher means causes the next,

y fingers 17 3. The folding fingers 62 are then or second, pusher member 54 'in order to engave and movethe butter bar forward to a point adjacent to the end folding members 51. This movement of the butter bar causes it to engage the tissue sheet P and carry it forward therewith, the upper and lower edge portions of the sheet being folded over and under th`e butter bar by the folding members 47 and 48 (Figure 17). The next forward movement of thepusher member carries the butter bar forward to a point immediately to the rear of a carton E in the receiver 61a. The movement of the butter bar to this position causes the folders 50 and 49 to act on the upper and lower projecting end portions of the wrapper to fold them, one over the other, against the end portion of the wrapper' which was turned rearwardly againstthe'end'of the butter bar by the folders 551. The end punches 51 then act on the end 'portions of the wrapper which'project rearwardly beyond the but? ter bar to fold them inwardly against the rear side of the bar'. The next pusher member 54 in order then moves u ward and forv ward, causing a folding of tie bottom rear;

wardly projecting edge portion ofthe wrapper againstthe rear side of the butter bar and forces the butter bar a ainst the central panel F ofthe carton causing the folding member 61 to act agalnst the upper and lower portions of the carton to fold them respectively over and under the butter har. This movement of the usher means forces the butter bar and em racing parts to the position shown in Figure 6, where it is stopped'by an engagement with the stop swung downwardly to fold the edge da H downwardly against the rear sidel o the butter bar, such folding movement carrying 4the rearwardly projecting upper edge portion of the wrapper sheet therewith. The

arm 1530 is then swung downward to the after which the folding nngers o2 .are elevated and at approximately the saine time ppsition shown in Figure 22 to hold the Hap the stop ters 173 are elevated. 'lhe first lill 'the position slr-o reaching tl-7s 'position th forward s hy ward against -w 1 i 1e end il flaps .la move respeetively over and under the stationary anvils 91 and 92. The folding arms 81 and 82 are then actuated to brea the, tongues M over the anvil edges to place i Y250 and 251 respectively, (Fig. 2) which hold the tongues against the guides. During the movement of the butter liar to this position,'the end flaps J and K are held folded by the engagementof end guiding bars 240 thereagainst which bars retain such engage- Iment until after the butter bar has moved from this position. 'lhe end-liep' guiding or holding bar s240 are carried hy, and constitute extensions from, the stationary fold*- ers 70. rlhe folding plates then act against the res ective end deps lh and cause an inward fol ing of such daps and anoinsertionof the tongues M into the respective ends of the carton.

The next movement of the hars which is actuated by the pusher means causes an ejection of the carton enclosed butter har from the machine and moves such butter hars from en agement with the end bars 240.
